. BRAKING MECHANISM Application filed June 26,

which the following isa specification.

My invention relatesto brakes for vehicles and in automobiles.

The object or" ,myinvention islto provide a brake that may be operated either manuallyl or automaticallyin case of sudden danger such as an obstruction being encountered in the roadway or a personstepping in front of the vehicle when in motion;

Referring to the drawings which form. a part of this specification,

Fig. l is aside elevational view of an automobile equipped with my brake apparatus illustrating the relative position 01" the parts when the brake is in operation.

Fig. 2 is a side view ofthe brake in normal position as carried on'the vehicle.

Fig. 3 is afractional front view illustrat ing in full lines the normal position of the buiier portion and in dotted .lines'the set positio Fig. 4 is a sideview of the buffer portion,

' the dotted lines indicating the position of" the parts in set position.

Fig. 5 is a side elevational View of the brake on a'larger' scale to more clearly show the arrangement of the several parts.

A indicates the bodyportion of an auto mobile and B the chassis'on which it is JDOUllbGtl. C indicates a longitudinally extending portion of the frame of the car, or in some cases aspecialframe carried by the chassis and on which the brake mechanism is mounted. The brake mechanism com- ;rises two units of like construction, one of each which is carried on each side oi the vehicle in front of the driving wheel's. The description of one part will therefore sufiice for both, their operation,beingsimultaneous and both being released for action by the same lever or buffer. I I

The mechanism is reset by manually lifting the parts into inoperative position after which the spring R is compressed and the pawl S placed in position.

If desired, the brakes may be applied by ll manually, as will be readily understood. it is to be understood that this emergency brake is not intended to be operated when the vehicle moving at a high rate of speed but is intendfl more for protection to pedestrians who carelessly step in front of a vehicle when the same is moving at a moderate rate through a crowded street or where the vehicle is started just as a person starts to cross in front of it, as otten occurs.

Small details of construction have been omitted from the drawings as not necessary to a person skilled in this art and I reserve the right to change or modify the construction as same may be necessary to fit (llllfent types of vehicles, depending upon i; claims forming a part oi this specification to define the limitations.

claim as new and desire to secure by lat ters Patent 1. A brake mechanism for road vehicles comprising a supporting frame, a brakeirame carried thereby, means for liolr'iing said brake-frame at a predetermined distance above the ground, comprising a bellcrank lever having a slot at one end and connected to said brake-frame by a pin adapted to slide in said slot, a locking mechanism controlling said brake-frame and means for automatically unlocking said lock and thus setting the brake.

2. A brake mechanism for road vehicles comprising a supporting frame, a brakeframe carrying a brake-shoe adapted to contact with the surface over which the vehicle is passing and means for releasing said brake-frame from said supporting frame, said means comprising a lender having side levers carried by said supporting frame, a

locking mechanism comprising a rod and awl, and flexible wires extending from the endsof the fender levers to said pawl.

8. A. brake mechanism for road vehicles comprising a supporting frame, a brakeframe carrying a brakeshoe adapted to concoinprising supporting :trane,

levers carried. by said supporting r'raniie, a

locking mechanism comprising a rod and pawl, and flexible wires extending from the ends of the tender levers to said pawl, and a lever adapted to be manually operated also arranged to operate said pawl to release said brake-frame.

4-. A brake mechanism for road vehicles comprising a supporting frame, a brake frame carrying a brake-shoe adapted to contact with the surface over which tiie vehicle is passing, and ineans for releasing said brake-tame from. said supporting frame comprising a locking mechanism having a rodandvp'awl, a spring adapted to actuate said red when the pawl is withdrawn to release said rod and suitable connections tor holding the rod and brake-frame in operative relation.
